What does this tool do?

It takes raw JSON and either pretty-prints it with 2-space indentation for readability or minifies it into a single compact line for production use.

Does it validate my JSON?

Yes. If your input is not valid JSON, the tool will show an error message indicating the problem. Only valid JSON can be formatted or minified.

The formatter uses 2-space indentation, which is the most common convention for JSON files.

No. All formatting and validation happens locally in your browser. Your data is never transmitted anywhere.

Paste JSON to pretty-print with proper indentation or minify into a compact single line.
